<p>PROBLEM TO BE SOLVED: To provide an adhesive composition which has a short aging (hardening) time and is improved in productivity and an adhesive composition high in the ratio of plant-derived ingredients.SOLUTION: An adhesive composition consists of a polyurethane polyol which is obtained by reacting a polyol mixture comprising an aromatic polyester polyol and an aliphatic polyester polyol in a mass ratio of 10/90 to 70/30 with a polyisocyanate in a ratio of the molar number of isocyanate groups to the total molar number of hydroxy groups, [NCO]/[OH], of 0.2-0.9 and a polyisocyanate hardening agent.</p> |
